Comparison analysis of AVHRR albedo temporal changes and dust TSP data

摘要

Chinese and Japanese researchers established a joint project in 2000 to set up ground observation stations along dust source areas, transportation roads, and precipitation areas by collecting TSP (dry dust precipitation) and AVHRR data to retrieve albedo (surface energy). The selected data from retrieved albedo temporal imagery are used to construct LST/TSP/albedo curves. Finally a comparison was made between albedo curves and TSP curves. The result showed that there were good correlation between these two kinds of curves. It was proved that the albedo could be one of the physical parameters for predicting dust storm in future monitoring systems.
